The Back (including
Trapezes or Shoulders and
Deltoids or Upper Laterals)
Follow pad placement diagram. The 2 pads from one
channel should keep 1/4 inch gap inch from each
other. The pad near the centerline, should keep 1 inch
space from the centerline of the back.
This requires 2 pair of pads.
program 17 for 10-20 minutes,
program 9 for 10-20 minutes;
Frequency: 3 to 4 times per week.
(8)
The Buttocks and Back
Thighs
Follow the placement diagram. Make sure there is
about a 1/4 inch gap between the pads. This requires
2 pair of pads for Buttocks or 2 pair of pads for Back
Thighs.
program 22 for 10-20 minutes,
program 5 for 10-20 minutes;
Frequency: 3 to 4 times per week.
(9) Back
(Alternate stimulation for
the Shoulders and Lower
Back)
Follow pad placement diagram. Draw an imaginary
line down the center of the back. Using one channel
place the pads on the left side of the centerline. Put
one pad on the top and one pad on the bottom. Now
repeat the process for the right side using the second
channel. Make sure the pads are each about one inch
from the center of the back.

Problems Possible causes Try this solution
No. One pad feels stronger than the
other.
This is normal. Different areas of your
body will react differently.
Nothing needs to be done. Make sure the
pads are sticky and are making good
contact.
1 The intensity is not felt.
Very weak intensity level.
Pads are not attached to the body firmly. Attach both pads firmly to the skin.
The transparent films are still stuck to
the pads.
Peel off film on the adhesive surface of
pads.
The pads stacked together or overlap. Do not stack pads together or overlap
pads.
The cord is not properly connected to the
unit.
Connect cord correctly into the jack.
The intensity setting is getting weak. Increase the intensity level.
The battery capacity is low. Charge the battery.
2 The skin turns red or the skin
feels irritated.
The adhesive surface of pads is dirty or
dry.
Wash adhesive surface of pads softly
with your fingertips for about 3 seconds
under slow running water.
The therapy time is too long or the
intensity is set too high.
Reduce the application time or reduce
the intensity.
The electrode pad surface is worn out. Replace electrode pad.
3 No power source; no display in
LCD.
The battery capacity is depleted. Charge the battery.
4 Power cut off during use. The battery is weak. Charge the battery.
The cord is broken. Replace the cord.
5 It is difficult to attach the pad
to the skin.
Have you removed the transparent film
from the pad?
Peel off film on the adhesive surface of
pads.
Was the pad applied immediately after
washing?
Dry the pad.
Is the adhesive surface of the pad
damaged?
Replace the pad.
6 Adhesive surface of pad is not
sticky.
Are you using pad when perspiring? Use when not perspiring, in a cool room.
Were the pads stored under high
temperature, high humidity, or direct
sunshine?
Replace the pad.

2) The manufacturer is only responsible for the safety and performance of the TENS and Muscle Stimulator when
readjustments, alterations and repairs are carried out by authorized individuals and when the TENS and Muscle Stimulator is
used in accordance with the user instructions.
3) Qualified technicians who are familiar with the technical features of the device have been provided with circuit diagrams,
PCB drawings, component lists and setting instructions by the manufacturer.
2. Cleaning and maintenance
A. For the main unit:
1) To keep the controller clean, use a soft and dry cloth for dust or a soft damp cloth for any dirt and smudges. Do not use any
cleaning solutions to clean the controller and its pads.
2) Do not use or store the device where there are magnetic fields or electric waves (near TV set or speakers).
3) Do not place the devices in areas of high temperature, high humidity, or under direct sunlight.
4) Keep the device out of reach of children.
5) All worn accessories should be disposed of according to your local regulations.
B. For electrode pads:
* Refer to the user manual of the pads manufacturer (K152648 & K181234), or reference to the following suggestions:
1) Unplug the output cord from the output jack of the controller after each use. Cover both pads with the protective film before
storage. Never fold the electrode pads.
2) Between uses, store the electrodes in the reusable bag in a shady place. Stockroom temperature: +5°C~+27°C (41-80°F) and
humidity of 30%~80%. No need to sterilize.
3) Never apply the pads to any other surface other than your skin.
4) The life of the electrodes varies depending on skin conditions, storage, amount of use, type of stimulation, and stimulation
site.
5) When the electrodes dry out and do not stick, buy new pads compatible with TENS and Muscle Stimulator, with smallest
area of 25cm2.
Regards buying new pads, you can contact our local device sell center, or you can contact the following electrode manufacturer,
they will tell you the local address where you can buy them. Or you can buy other 510(k) cleared electrode pads with smallest
area no less than 25cm2.
Warning: The electrodes are intended for single patient use only!
C. For Cables
1) Disconnect the cables from the stimulator and electrodes.
2) Do not pull on the cables; only pull on the connectors attached to the ends of the cables.
3) Store the stimulator with the cables in a clean, dry place.
3. Storage
Caution: Do not store in a damp area. Dampness may affect the device and cause rust.

VI. Electromagnetic Compatibility
Important information regarding Electro Magnetic Compatibility (EMC)
With the increased number of electronic devices such as PC and mobile (cellular) telephones, radio transceivers, mobile
radio transmitters, radio-controlled toys, and so on, Medical devices in use may be susceptible to electromagnetic interference
from other device. Electromagnetic interference may result in incorrect operation of the medical devices and create a
potentially unsafe situation. Medical devices should also not interfere with other devices.
In order to regulate the requirements for EMC (Electro Magnetic Compatibility) with the aim to prevent unsafe product
situations, the IEC 60601-1-2: 2014 standard has been implemented. This standard defines the levels of immunity to
electromagnetic interference as well as maximum levels of electromagnetic emissions for medical devices.
This unit has been thoroughly tested and inspected to assure proper performance and operation! This product needs
special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided,
the following tables recommend minimum separation distances between portable and mobile RF communications equipment
and the TENS unit.
Caution:
* The use of accessories and cables other than those specified by the manufacturer , with the
manual
